Embodiment 1

[0026] Example 1: Preparation of CLP-urea gel and investigation of its influence on nitrogen absorption and utilization

[0027] 1. Preparation of CLP-urea gel:

[0028] Mix urea and water according to the ratio of 1g:10ml (W / V) to form a urea solution. Mix the urea solution and the CLP brake carrier according to the ratio of 60ml:1g (V / W) to make CLP-urea gel.

[0029] The particle size of the CLP-type braking carrier used in the preparation of CLP-urea gel is <0.3mm, and it is from Beijing Hanli Miao New Technology Co., Ltd.

[0030] 2. Effect of CLP-urea gel on nitrogen absorption and utilization

[0031] During afforestation, 4 treatments are set, respectively (1) get 120g CLP-urea gel and place it at the bottom, and 250g CLP-urea gel is evenly placed around the root system of the arborvitae container seedlings (experimental group); The CLP brake carrier with the same quality as the group absorbs the same amount of water as the experimental group, and urea with the same...

Embodiment 2

[0034] Example 2: Preparation of CLP-Z77 gel and its effect on the diversity of bacterial community structure in rhizosphere soil and the adaptability of plants in arid environment

[0035] 1. Preparation of CLP-Z77 Gel

[0036] Bacillus cereus (Bacillus cereus) Z77 was subjected to seed culture and liquid fermentation culture according to conventional methods to obtain Bacillus cereus Z77 fermentation broth. Dilute the fermentation broth of Bacillus cereus Z77 so that the number of effective viable bacteria is 3.2×10 7 cfu / mL Z77 bacterial liquid, mix the diluted Z77 bacterial liquid and CLP type brake carrier according to the ratio of 30ml:1g (V / W) to form CLP-Z77 gel.

[0037] The particle size of the CLP-type braking carrier used in the preparation of CLP-Z77 gel is 0.3-0.8 mm, and it is from Beijing Hanli Miao New Technology Co., Ltd.

[0038] Bacillus cereus (Bacillus cereus) Z77 has been preserved in the General Microbiology Center of China Microbiological Culture Col...

Embodiment 3

[0043] Embodiment 3: Afforestation test

[0044] Make CLP-urea gel and CLP-Z77 gel according to the method of embodiment 1 and embodiment 2 respectively, arrange afforestation test in Niuwangquan Beishan, Miaoshan Town, Beimiaoshan Village, Laicheng District, Laiwu City, in July 2012 Arrange afforestation experiments on the 10th. Afforestation seedlings are selected from container seedlings of oriental cypress. After digging the tree holes in batches, take 120g of CLP-urea gel and 40g of CLP-Z77 gel and sprinkle them on the bottom of the pit, and take 280g of CLP-urea gel and 80g of CLP-Z77 gel and spread them evenly around the root system of the container seedlings . Only add CLP-urea gel with the same mass as the experimental group (control group 1) and only add CLP-Z77 gel with the same mass as the experimental group (control group 2) as a comparison. The survival rate was investigated in the year of afforestation, and in the following year. The results are shown in Tabl...

Abstract

The present invention discloses a substrate capable of improving the survival rate of afforestation in a drought and barren mountainous region. The substrate consists of a CLP-urea gel and a CLP-Z77 gel; the CLP-urea gel is prepared by uniformly mixing a urea solution and a CLP braking carrier in a proportion of (50-80)ml:1g, and the urea solution is absorbed by the CLP braking carrier, thus the CLP-urea gel is formed; the CLP-Z77 gel is prepared by uniformly mixing a bacillus cereus Z77 solution and the CLP braking carrier in a proportion of (15-30)ml:1g, and the bacillus cereus Z77 solution is absorbed by the CLP braking carrier, thus, the CLP-Z77 gel is formed. The present invention further discloses a method for afforestation in the drought and barren mountainous region by adopting the substrate. By adopting the substrate and the method, the survival rate and preserving rate of afforestation are remarkably improved.

Description

technical field [0001] The invention relates to a substrate and a method for improving the survival rate of afforestation in arid and barren mountainous areas. Background technique [0002] The area of ​​arid and semi-arid regions in the world accounts for about 35% of the land area. The arid and semi-arid regions in my country are vast and account for about 52.5% of the total area of ​​the country. The resulting land desertification has made my country one of the most serious desertification hazards in the world. The arid and barren mountainous area is one of the most difficult areas for vegetation restoration, with low survival rate of afforestation and serious soil erosion. Soil drought and barrenness are the main limiting factors affecting vegetation recovery in these areas. Therefore, improving plant drought resistance and nutrient utilization efficiency is a key measure to improve the ecological environment in these areas. [0003] Aiming at how to improve the drough...
